Layer-by-layer electrosynthesis of Pt–Polyaniline nanocomposites for the catalytic oxidation of methanol Palmero Díaz, Susana; Colina Santamaría, Álvaro; Muñoz, Emma; Heras Vidaurre, Aránzazu; Ruiz Fernández, Virginia; López Palacios, Jesús A new composite material based on the electrochemical generation of a layer-by-layer structure of polyaniline (PANI) and Pt particles has been prepared. The number of layers and the nature of the external layer (PANI or Pt) determine the electrocatalytic performance of the composite for the oxidation of methanol. We demonstrate that the layer-by-layer approach to form the nanocomposite and modification of the Pt particles with a layer of PANI leads to substantially higher catalytic efficiency.

Bidimensional Spectroelectrochemistry López Palacios, Jesús; Colina Santamaría, Álvaro; Heras Vidaurre, Aránzazu; Ruiz Fernández, Virginia; Fuente, Luis A new methodology is presented to offer the possibility of simultaneously obtaining two different spectroscopic signals in a single spectroelectrochemical experiment. Taking the plane of the electrode surface as a spatial reference, normal-beam and parallel-beam UV−vis absorbance signals are jointly analyzed, revealing important experimental differences between the two kinds of signals. Two different chemical systems are selected to show the possibilities of the bidimensional spectroelectrochemistry:  a simple diffusive process and an adsorptive electrode reaction. Comparative results show clearly that the two kinds of spectroscopic signals, both normal and parallel to the electrode surface, have to be used together in the study of any electrode reaction scheme.

Dataset of the work “Determination of nicotine in e-liquids by electrochemical generation of surface-enhanced Raman scattering substrates” Romay García, Luis; Pérez Estébanez, Martín; Heras Vidaurre, Aránzazu; Colina Santamaría, Álvaro Quantitative methods using surface-enhanced Raman scattering (SERS) for analysis in complex matrices are very attractive due to the high sensitivity and selectivity of this technique. In this work, a novel time-resolved electrochemical surface-enhanced Raman scattering (TR-EC-SERS) analytical method has been developed for the determination of nicotine in e-liquids of electronic cigarettes. One of the main challenges of SERS is its inherent lack of reproducibility. Here, this limitation was mitigated by employing an electrochemical pre-treatment step to generate a homogeneous distribution of silver nanoparticles (Ag-NPs) on a silver screen-printed electrode. The enhanced Raman scattering induced by the Ag-NPs enabled the detection of nicotine at nanomolar levels. The high sensitivity of the method allowed the quantitative analysis of diluted e-liquid samples, mitigating potential interferences from other components present in these complex matrices. Moreover, TR-EC-SERS, coupled with parallel factor analysis (PARAFAC), demonstrated the capability of trilinear spectroelectrochemistry data not only to detect nicotine but also to identify potential interfering compounds without prior knowledge of their spectral signatures. This multivariate approach offers significant potential for the detection of outliers in complex samples.
